The DPK6 duct probe units have been developed to detect smoke in ventilation ducts and offer significant benefits in terms of performance and installation. For most applications, smoke or combustion products are likely to have travelled some distance ageing the smoke prior to reaching the probe unit. It is therefore normally recommended that an optical smoke detector be fitted, and this is often a requirement of building regulations. The DPK6 duct probe units use FC460PH Multi Sensor Smoke Detectors.
The DPK6 Duct Probe units are not normally mounted directly inside ducts because the airflow only allows the detector to sample air from a small section of the duct and such detectors would rapidly become dirty. Instead, ducting is protected by the use of probe units which gather air from a cross section of the duct and pass it through a smoke detector head.
The system comprises only one single duct probe tube which improves efficiency and reduces installation time. The DPK6 duct smoke detector housing is designed to comply with the stringent demands of new European standard EN 54-27. The system fulfils all the requirements for safe fire detection with airflow speeds from 1,5 m/s to 20 m/s.
For the airflow through the adaptor to be representative of the airflow in the ventilation duct, the detector should be installed at a place where normally flow meters etc. are sited.
